In Peru, like many Latin American countries, executives workers often do not eat at home for lack of time and long distances. In this sense, they eat in restaurants that offer daily meal popularly called "Menu". One of the most popular restaurants in Peru is the "Chifa" which is Chinese and Peruvian fusion food, usually seen that diners to finish eating the dishes leave at least one third of the food, and this is discarded. By observing and asking diners, the reasons were diverse as:
"They served too much food"
"I do not like vegetables but always serve this dish"
"I do not have time to finish the dish"
We believe that these reasons reveal many important points because the food is discarded.
